Structurally the two receivers of the Model 870 Express and Model 870 Police are identical. The only difference will be that the Police model will have a more durable finish. The magazine tubes will be slightly different. The Model 870 Express will have two indents in the magazine tube to accommodate the new style plastic magazine spring retainer. However, this prevents the Express model from accepting a magazine tube extension without alteration to the tube.
Other differences to the Police model include sling swivel studs, a shorter fore-end, heavier shell latches, a heavier sear spring and a heavier magazine spring.
